"The climate, health and tax law passed with only Democratic votes is projected to lower U.S. emissions 40 percent by 2030, down from 2005 levels, modeling experts and economists say, and the laws on computer chips and infrastructure may also help slash emissions.

Erin Mayfield, a Dartmouth College engineering professor, said the climate law could avoid more than 35,000 premature deaths over the next decade, an economic benefit of $300 billion.

It could also create 1.7 million jobs by 2030 and “spur record-setting growth in wind and solar capacity,” Mayfield said.
